FORMS FOR REILlFORCED-GDH CRETE WALL AND COLUMN CONSTRUCTION.

.IT 0 all whom it may concern I Be" it known that I, Gnoncn E. DALE, acitizen of the United States, and a resident of Trenton, Mercer county,New Jersey, have invented Improved Forms for Reinforced-Concrete Walland Column Construction, ofwvhich the following is a specification.

My invention relates to forms, molds or centering for concreteconstruction; and the object of my invention is to provide an improvedform supporting means for wall and I column construction.

My invention consists in the use of metallic members of flat, angle andchannel form suitably braced and supported, and adjustable for thepurposes described.

My invention is fully shown in the accompanying drawings, in which:

Figure 1, is a plan view of a wall support or centering means embodyingmy invention: Fig. 2, is a perspective view of the same; Fig. 3, is aplan view of a column centering form embodying my invention; Fig. 4, isa perspective view of the same; Fig. 5, is a perspective view of theupper portion of a column centering form embodying an'importantmodification of my invention; Fig. 6, is a plan view of the same, and Fi7, is a. sectional elevation thereof.

n a companion Patent, No. 1,131,479,

dated March 9, 1915, I have described the use ofmetal members orsections as centering for :floors', beamsor girders and lintels. Mypresent invention relates to formsorcentering for wallsand columns, andfor such purpose I employ'metal channels and angles in combination withflat metal plates, with means for holding the same in proper positionwhen assembled for the purpose desired.

Wall forms or centering embodying my invention are shown in Figs. 1 and2, and they may comprise channel sections 1, which alternate with plates2, the latter lapping or overlying the channels as indicated. At thecorners of the wall form, angles 3 may be employed. The members formingsuch wall form will be spaced. the proper distance apart and may be heldin proper relationship with respect to each other .by

means of wire ties 4, as clearly shown in Figs. 1 and 2. The channelsections 1 are preferably disposed with their flanges 5 projectingoutwardly as indicated, and to stiffen such wall forms and at the sametime maintain a substantially unbroken surface, I provide flat bars 6which lie against the flat webs of the channels and pass through slots 7cut in the flanges of said channels. In order that the bars may lieclose to the webs of the channel, the slots may extend part way intosuch Webs. To maintain the bars against said webs, I may employ wedges8, which may be driven into the slots of the channel flanges directlyagainst the bars 6, as shown. The slots in the flanges of the channelsections will be preferably disposed. in proper relative position inorder that the bars from adjacent walls may be carried across each otherand be secured by suitable means; for instance, by pins 9 as shown, suchpins entering registering apertures 10, of which each bar has a. series.The wire ties +2 will be left embedded in the concrete and they may be.cut away from the metal forms when it is desired to remove the latter.The form for the inner corner of the wall may have angle sections 11,secured thereto as indicated, in order that it may be brought intoproper relationship with respect to the next channel sections to bebraced by the bars 6.

The column form shown in Figs. 3 and 4-, is preferably made (it a seriesof metal angle members 12, substantially ,W-shape in cross section,which members are placed together in position to form a hollow space tobe subsequently filled with concrete to form a column. The metal anglemembers may be relatively small, and may serve primarily for the supportof flat metal plates 13, which provide the actual sides or walls of thecolumn'form; and these plates may be'secured to the angle sections 12 inany approved manner. By preference, the outwardly extending flanges 14of said angle members are slotted at 7 in the same manner as the flanges5 of the channel sections of the wall forms, and bars 6 are provided topass through said slots and lie against thewebs of the angle members. Tohold the bars against said angle members, I may provide the wedges 8,and the bars will be held in place with respect to each other by meansof pins 9, entering registering apertures 10, of which each bar has asenes.

In the use of the metal wall and column forms, the bracing bars will beused at frequent intervals. The wall forms will be of standard length,and of such aweight of metal as to be capable of overlapping without'aflecting unduly the normally flat surface of the wall to be formed.The column forms will also be of standard length, and I prefer toprovide ad ustable and removable extension means for the same when acolumn 3 and 4.

of greater height than that provided by the standard length forms is tobe constructed,

such corners. In Figs. 5, 6 and 7, I show an arrangement of columnform's comprising plates 15 having portions 16 bent at an angle theretoand arranged so as to lie against the flat surface of another plate I5disposed at right angles to the first. This arrangement" 'is carried outwith respect to all the plates comprising the sides of the form. Inaddition each plate is provided with an angle piece 12 riveted. orotherwise secured to said plates adjacent the bent or turned upportions. 16, and having outwardly extending flanges 14. This form ofstructure will be held together by the bars 6 and pins 9 in the samemanner as that illustrated in Figs.

The column-forms will be of standard length which may be in someinstances too shortfo'r the height of the column desired. In such caseit is necessary to provi de extension means for the upper end of 'saidcolumn form. For this purpose I prefer sections of Wood, whichmay be ofvarious heights to properly complete the desired dimensions of thecolumn. To support the wooden sections, which are shown at20, themember's composing the side Walls of the form-shown in Figs. 5,6 and 7are provided. with brackets 21, which may be secured thereto in anysuitable manner, by

riveting, as indicated at 22, for instance, or by other suitable means,and such brackets should be of such shape and dimensions as to properlysupport the wooden extensions with their inner-faces flush with theinner' faces of the. metal portions of the forms.

The extensions. will also be constructed. to provide the desiredchamfered edges for the column.

Should the walls or column forms require lateral support they may bebraced from the floor-by suitable means. I11 the case of the wall forms,the braces may engage the flatbars used for stiifening purposes. Inother instances it may be desirable to secure brackets to the metalmembers which will serve as means for the application or attachment ofsuitable shoring. The metal wall forms shown in Figs. 3 and 4 may beprovided with the same kind of brackets illustrated in Figs. 5 and 7, inorder to increase the height of the same Without th use of full-sizedsections.

The metal members of the wall and column forms may be of such weight ofmetal f as to overlap readily without making bulky joints or, I mayarrange to butt the succeeding sections and provide vertically disposedstays or stiffening members to maintain the several sections in properposition and place. In some cases it may be desirable to proticalsections, although I prefer a single standard section which may or maynot have the extension means. i

It will he understood that the concrete to be poured into the severalforms will be reinforced by metal rods or bars.Such'r'einr'orcingmembers will be spaced and stayed by suitable meanswhich may or may not engage the walls of the forms. U

The column forms. as well as the wall forms \\'lll he of a characterthatmay be readily fitted into place in combination with the floor andgirder or beam ce'nterin forms of my companion application filed 0? evendate herewith.
